  • Use only the recommended batteries. Always replace weak or empty batteries with a new, complete set of batteries at full capacity. Do not use batteries from different brands or with different capacities. The batteries should be removed from the unit if it has not been used for a long time.


Weather station, 3x Outdoor sensors, Operating instructions, DC 5V 150 mA Adapter, 9x AAA batteries.


  • We recommend using alkaline batteries. If temperatures regularly fall below 0°C (32°F), we recommend using lithium batteries.
  • Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain correct power requirements.)
  • Insert batteries before first use, matching the polarity in the battery compartment. 3x AAA Batteries are required for the Weather station and 2x AAA Batteries are required for the Outdoor sensor.

  1. Remove the battery door from the back.
  2. Insert 3x AAA (LR03)/1.5V batteries. Please ensure the polarities (+/-) of the batteries match upon installation.
  3. Reattach the battery door.

NOTE: Replace batteries when [ ] when the display is dim.


The main unit can receive data from up to 3 outdoor sensors. 3 sensors are included with delivery.

  1. Remove the battery door from the back.
  2. Select a channel.
  3. Insert 2x AAA (LR03)/1.5V batteries. Please ensure the polarities (+/-) of the batteries match upon installation.
  4. Reattach the battery door.
  5. Place the sensor within 30 m (98 ft) of the main unit using the table stand or wall mount.


The main unit will automatically search for a new sensor after the batteries are installed. The receiving process is 3 minutes. During receiving process, the antenna icon [ ] is flashing. Once receive signal, monitor will receive the outdoor temperature and humidity at the same time.

Press and hold [ CH ] to re-register RF data.

If RF registration failed or missed for more than 1 hour, the data will flash “–.-“.To manually initiate an outdoor sensor search, press and hold [ CH ].

NOTE: The transmission range may vary depending on many factors. You may need to experiment with various locations to get the best results.



  1. When you insert or replace the batteries, RCC reception is initiated. To manually start RCC reception, press and hold the [ DOWN ] button.
  2. After the RCC receives the signal, if you change the relevant display settings (such as year, month, day, hour, minute, etc.), the RCC symbol [ ] will automatically disappear.
  3. If the RCC receiving process is successful, a completed RCC symbol [ ] will be shown in the display and the date and time will be set automatically. If it fails, press and hold the [ DOWN ] button to re-initiate RCC receiving.
  4. RCC receiving will automatically start from 1:00 – 5:00 every night. Auto receiving function will cease if it is successful. If it does not receive the RCC signal, it will receive in next day.
  5. If the device is still not receiving the signal, please proceed to set the time manually.
